Sumitomo 1GRB002 Cutoff Insert Wcf AC830P Carbide

Product Description

The SUMITOMO 1GRB002 is a solid carbide cutoff insert in the WCF series, designed for parting, grooving, chamfering, and cut-off operations on CNC lathes and turning centers. It carries manufacturer grade AC830P with a CVD coating, delivering consistent wear resistance and thermal stability in demanding cutting environments. The insert features a 0.1575-inch cutting width, a neutral lead angle (0 degrees), and a corner radius of 1/128 inch. Clamp-style holding secures the insert firmly in compatible WCF-series toolholders. This insert is suited for machinists and toolroom technicians working in production and job-shop turning applications.

The 1GRB002 is rated for primary workpiece materials including stainless steel and steel (ISO material codes M and P). Material grades C5, C5A, and C6 apply, making it appropriate for a range of ferrous turning and grooving tasks. It is well suited for light-duty parting and chamfering passes where a narrow cutting width and neutral geometry help control chip formation and cutting forces. The multi-use designation means a single insert can serve across chamfering, cut-off, and grooving setups without changing tooling.

Key Features

• Solid carbide construction with AC830P CVD coating for wear resistance in steel and stainless steel cutting
• 0.1575-inch cutting width with neutral (0-degree) lead angle and neutral hand orientation
• Corner radius of 1/128 inch for controlled edge geometry
• Clamp-style insert holding method compatible with WCF series toolholders
• Multi-use insert suitable for chamfering, cut-off, and grooving in a single setup
• Applies to material grades C5, C5A, and C6 across ISO P and M workpiece categories

Compatibility

Designed for use with WCF series insert toolholders that accept size-4 clamp-style cutoff inserts. Confirmed for machining stainless steel and steel workpieces within ISO material codes M and P.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician with the machine powered down and locked out before changing inserts. Seat the insert fully in the pocket and verify the clamp is torqued per the toolholder manufacturer's specification before resuming cuts. Inspect the insert pocket and clamping surfaces for chips or debris prior to seating a new insert. Follow applicable shop safety procedures and machine-specific tool-change protocols.
